Well, just think about it a minute.
What is the alternative?
How do you think it is possible to round up, jail and deport over 11 million people? That is twice the population of Denmark and more people than many states have in population!
We can't even find the "FBI's 10 Most Wanted" or roundup and jail the drug lords and dealers in our cities and towns.
First, we must make our borders secure by hiring more well-trained border patrol agents (and get rid of those militiamen whackos with their camoflage and beer bellies). We must computerize ALL of our border crossings and increase passport and immigration security in those places.
Then, we MUST start arresting, imposing fines upon, closing and prosecuting those corporations in our country who HIRE undocumented workers. We must close the "bus-stops" where the employer drives along looking for people to hire off the street.
Once our borders are more secure, our passport and immigration security actually works, the corporations and companies stop hiring the illegals, then we can start on an amnesty program for those already here.
Ya know what, though? It ain't never gonna happen. Our government doesn't really give a good gosh-darn about it. They know that their good buddies in the corporate and agricultural world need this cheap labor force and they will do nothing to stop it. What you hear coming from their mouths are just words to make you and me feel like they care. That billion dollar "fence" they are building is only 7 miles long. NOTHING will stop the flow until there is no place here for them to work - and that won't happen as long as the employers get a wink and a nod from government.
